Column graphs
Column graphs are similar to bar graphs though the columns are presented
horizontally rather than vertically.
The column graph is more similar to the bar graph in that it is used more for one time or single events rather than continuous events.
In a column graph the data is literally presented in columns. The category names can be on the graph or underneath the column. It is not necessary to assign different colours to the columns ,although one could do so and then attach a legend that would explain the different colours and which category they stood for.
